What is a .PART file?
A .part file is an unfinished download, renamed once it completes. Created by Firefox and other apps.
- Did you know
- Firefox and other browsers add the .part suffix while a download is still in progress.
- The .part convention long predates browsers - download managers and FTP clients have used a temporary suffix for decades to mark a transfer as still in progress.
- Because a .part is an incomplete copy, it is normally unusable until the download completes.
- What Analyser reads
- Identify BitTorrent files (TORRENT) and their file list, plus partial or incomplete downloads (PART, CRDOWNLOAD).
- Depth of analysis
- .PART is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .PART file
- Drag a .PART file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
